-- Information about the crash:
- What I was doing when the application crashed:  I had 3 tabs open in one Konsole window.  I had set the history length to 10000 in one of the tabs by clicking "Edit Current Profile..." in Settings.  I used that tab for several commands before going to a second tab (it already existed).  I did some commands with lengthy output and noticed it wasn't retaining 10000 lines.  I checked the settings for the second tab, discovering it still had a 1000 line history (yes, I'm new to Konsole :).  I again set the history for "current profile" to 10000 lines.  I went into "Manage Profiles..." in Settings and discovered my actions had created two new profiles (Profile 1 and Profile 2).  I renamed Profile 1 to "Local standard".  I then highlighted Local Standard and clicked "Set as Default".  Konsole crashed immediately.

I started a new Konsole instance and noticed that the rename had been successful, but not changing "Local standard" to default.  This time I was able to set "Local standard" to default and also remove "Profile 2" without incident.

The reporter is unsure if this crash is reproducible.
